Hi @casperdcl

The version3 in mcr.microsoft.com/devcontainers/ruby:3-trixie, actually comes from the semantic version of the dev container ruby image. More details on the versioning here. I understand this is little confusing as the ruby version coincides with the semantic version of the image. Please let me know in case of further concern.

Ah, in which case I have a minor feature request for ruby/manifest.json... it has a ${VERSION}-4-trixie tag variant, but missing a ${VERSION}-3-trixie
